"Well done, students", said Master Wu,"You have completed your quests and brought some Herovillians here to stay with you. We would like to welcome them to Ninjago and we'll give them a tour all over Ninjago".
"Thank you, Master", said Kira bowing down as respect,"It would be our honor to have a tour around Ninjago".
"As the children of the ninjas of Life and Future, we promise to be disciplined, polite and respectful", said Raphael bowing down as respect.
"Thank you", said Master Wu as he gives them a tour.
They all lived happily. This is not the end of the story. They will have more adventure.
